Five numbers, and the one line that tells you why each matters to a business decision this week.
Announced, gazetted, scheduled or statutory — not forecast.
The review file is not considered final until close of business September 7. This file shows exactly which stocks will be added to or removed from the FTSE Frontier index — and therefore which names see index-tracking flows on September 21.
Employers must remit Pay-As-You-Earn deductions to FIRS (federal employees) or the relevant State IRS by the 10th of the following month.
Three events on one date: monthly VAT and withholding tax filing (₦200,000 NTAA penalty for missing it), Nigeria's return to FTSE Frontier Market status from the market open, and the start of the CBN's 307th MPC meeting (decision expected 22 Sep).
Annual returns fall due 42 days after 15 August each year, landing on Saturday, 26 September 2026. No CAC confirmation that weekend dates roll to the next business day.
Ordered by how quickly they hit your bank account. Everything here happened, or was formally disclosed, in the week of 1–4 September 2026, with market data updated to 5 September where it moved materially afterward.
The Stanbic IBTC Purchasing Managers' Index rose to 54.3 in August from 52.5 in July — matching the March 2025 reading as the strongest since early 2024. New orders hit a one-year high, output growth accelerated, and purchasing activity rose. Job creation remained muted. Inflationary pressures ticked higher. Business conditions have now strengthened for seven consecutive months. Data were collected 12–26 August 2026. The PMI is endorsed and adopted by the National Bureau of Statistics.
The PMI is the most direct, timely survey of the Nigerian private sector — 400 businesses across agriculture, manufacturing, services, construction and retail. Seven consecutive months above 50 is not noise; it is a pattern, and the acceleration from 52.5 to 54.3 is the clearest demand signal available. The new-orders component hitting a one-year high matters more than the headline: it tells you what is coming, not what already happened. The muted employment growth against rising orders, however, suggests businesses are meeting demand with existing capacity or overtime rather than hiring — a window that closes if the trend holds.
Use the 54.3 print as the operating-environment reference in any capacity, hiring or credit conversation this week. It is current, NBS-endorsed, independently compiled, and almost certainly stronger than whatever assumption your bank is using to assess your business.
The NFEM rate reached ₦1,315.67 on Thursday 3 September — the strongest level in approximately two years — before easing to ₦1,321.22 on Friday. External reserves crossed $54 billion for the first time since December 2008, reaching $54.08 billion on 3 September, up $8.51 billion year-to-date from $45.57 billion on 2 January. The reserves position is now $3.04 billion above the CBN's full-year projection of approximately $51.04 billion, with four months remaining. IMTO remittances hit a record $947 million in July, approaching the CBN's $1 billion monthly target. The parallel market held at ₦1,400–1,410 throughout the week, leaving the official-parallel spread at roughly ₦80–90, or approximately 6% — wider than the ₦63–68 recorded in our last edition.
Reserves at this level give the CBN firepower it has not had in 18 years. Combined with record remittance inflows and the FTSE reclassification due on 21 September (which is expected to bring additional portfolio inflows), the structural case for the naira's official rate is genuinely strong. But the widening parallel spread — growing even as the official rate improves — signals persistent structural demand outside formal channels. For an SME buying dollars at a BDC or on the street, the gap is now wide enough that the choice of channel is a material cost decision, not a convenience one.
Request your bank's posted corporate USD rate in writing today and compare it against both the NFEM print and your usual BDC source. If the spread is wide, this is the strongest environment in years to apply for a bank FX line — reserves are high, the official rate is firm, and the CBN has every incentive to keep supporting the formal window.
Dangote Petroleum Refinery raised its diesel (AGO) gantry price by ₦100 to ₦1,850/litre, effective midnight Friday 4 September. This follows the three consecutive petrol price hikes in late August (₦1,165 → ₦1,265). NNPC's Abuja pump price climbed to ₦1,345/litre, up ₦75 from ₦1,270 a week earlier, with Lagos at ₦1,225–1,299 and some private marketers above ₦1,300. However, imported PMS landing cost dropped to approximately ₦1,239/litre as of 1 September — ₦26 below Dangote's ₦1,265 gantry price — as the firmer naira reduced the naira cost of dollar-denominated imports. IPMAN's national publicity secretary stated on 3 September that cheaper imported stock could reach marketers within days.
Two opposing forces are now operating in Nigeria's fuel market simultaneously. Diesel costs are rising on global refined-product tightness and Middle East disruption — directly hitting manufacturers, cold-chain operators, construction and any business running generators. Petrol costs, meanwhile, may actually fall if cheaper imported stock reaches the pump, as the stronger naira makes imports more competitive against domestic refinery output for the first time. Businesses with mixed fuel exposure need to model both directions separately rather than assuming a single "fuel is going up" or "fuel is going down" narrative.
Re-budget all diesel-linked costs at ₦1,850/litre immediately. For petrol, verify directly with your marketer whether cheaper imported stock is available or incoming before committing to the current gantry-based pricing — IPMAN says it could arrive within days, and a ₦26/litre saving at volume is worth one phone call.
The NGX All-Share Index rose 2.36% for the week to 246,992.44, adding approximately ₦3.72 trillion in market capitalisation. Year-to-date return reached 58.72%. The NGX Oil & Gas Index led sectoral performance with a 9.10% weekly gain, followed by Consumer Goods (+3.52%) and Insurance (+3.85%). Breadth narrowed on Thursday — 22 advancers against 35 decliners — continuing the pattern of capital concentrating in expected FTSE constituent names while broader participation weakens. The FTSE Frontier Index Series review file changes are not considered final until close of business Sunday, 7 September. Reclassification takes effect from the market open on Monday, 21 September 2026.
The September 7 file finalization is the last piece of concrete, publicly available information before the effective date. It tells you precisely which stocks are being added to or removed from the FTSE Frontier Index — and therefore which names will see passive, index-tracking fund flows on and around September 21. That is not a forecast; it is a published constituent list. The narrowing breadth alongside the rising index is the detail worth tracking: a rally driven by a handful of large-cap names that happen to be likely FTSE constituents is a different story from a broad market recovery.
Track the finalized FTSE Frontier Index Series review file after close of business Sunday 7 September. That file is your best information edge — three weeks ahead of most retail investors — on which specific stocks will see index-driven flows on September 21.
September 2026 carries the densest compliance calendar of the year for Nigerian businesses. PAYE remittance for August is due Wednesday, 10 September. Monthly VAT and withholding tax returns (also for August) are due Monday, 21 September — the same day FTSE Russell's reclassification takes effect and the MPC begins its two-day meeting. CAC annual returns fall due Saturday, 26 September. The Nigeria Tax Administration Act's flat ₦200,000 penalty for missed VAT/WHT filings is already in force.
The clustering is the risk. Three filing obligations in 21 days, with the middle one landing on the single most consequential capital-markets date of the year, means finance teams focused on market positioning may miss the tax deadline sitting on the same morning. The PAYE obligation on September 10 is the one most often deprioritised by growing businesses — it falls earliest and has the least visible enforcement mechanism until it doesn't.
File PAYE by Wednesday 10 September. Then confirm your VAT/WHT filing process is ready for 21 September — do not let the FTSE news distract your finance team. Diarise CAC annual returns for Friday 25 September (ahead of the Saturday statutory date).
One rating for the operating environment a Nigerian SME faces going into the week of 7 September.
This is the first genuinely positive reading since July. The Stanbic IBTC PMI hit 54.3 — a 2.5-year high — telling you that 400 real businesses across Nigeria are reporting the strongest demand environment in 30 months. External reserves crossed $54 billion, an 18-year record. The naira firmed to ₦1,315, its strongest in approximately two years. The NGX rallied 2.36% for a second straight winning week. Four indicators pointing the same way at the same time is not routine.
The caution is targeted, not general. The parallel-market spread widened to ₦80–90 even as the official rate improved — a signal that the gains are not reaching everyone equally. Diesel jumped ₦100 to ₦1,850, directly raising costs for manufacturers, logistics and anyone running a generator. And the NGX rally's narrowing breadth (fewer stocks rising even as the index climbs) suggests capital is concentrating in expected FTSE constituent names rather than lifting the market broadly.
The forward calendar is unusually dense: FTSE review files finalize Sunday, PAYE is due Wednesday, and then 21 September carries a triple event — VAT filing, FTSE reclassification, and the start of the MPC meeting. The positive reading is real; the execution window is narrow.
Demand is growing, the currency is firm, and reserves give the CBN unprecedented recent firepower. This is the environment to stock up, hire and pitch — not coast.
A ₦100 single-day jump in diesel directly raises manufacturing, logistics and standby-power costs — with no relief timeline visible.
The first of three tax deadlines in 21 days, and the one most often deprioritised by growing businesses.
Twelve specific actions, ordered by deadline pressure. The dated ones are not optional.
The brief above covers what is confirmed. These are genuinely unresolved. We will report the answers, not guess them.
IPMAN's spokesperson said on 3 September that cheaper imported stock could arrive within days. Whether marketers pass on a ₦26/litre saving or absorb it as margin depends on competitive pressure, which varies by location. We are tracking pump-price surveys across Lagos, Abuja and Port Harcourt through the first September pricing window.
Two consecutive months of easing headline inflation (15.43% in July), a 2.5-year PMI high, and $54bn in reserves are all arguments for easing. But the MPC held through May and July despite similar moderation, and food inflation accelerated to 20.31%. A hold remains a live possibility. Credit conversations premised on a cut that doesn't arrive are a real risk.
Thursday's session showed 22 advancers against 35 decliners even as the index rose — continuing a pattern from August. If the rally remains concentrated in expected FTSE constituent stocks, smaller-cap names may see capital flow away from them rather than toward them. We will track breadth against the finalized review file after September 7.
Carried forward from our last edition. 42 days after 15 August lands on Saturday, 26 September 2026. We have found no published CAC statement confirming whether the deadline moves to the next business day. We are treating Friday 25 September as the safe deadline.
We never fake what we don't know. Here is what is verified, what is dated, what changed since our last edition, and where the gaps are.
The five developments cover 1–4 September 2026. Market data — the naira, reserves, the NGX close, and fuel prices — is updated to 5 September where it moved materially after the reporting week, and each figure is dated in the text and in the dashboard note.
We could not confirm whether the CAC annual returns deadline shifts off a weekend date, whether cheaper imported petrol stock has actually begun reaching marketers as IPMAN indicated, or the precise FTSE Frontier Index constituent list ahead of the September 7 file finalization. These are flagged above rather than estimated.
